Filter plates are one of the core components of filter presses, primarily used in the solid-liquid separation process to filter and withstand pressure. The design and materials of the filter plates directly affect the working efficiency and processing effectiveness of the filter press. Our company employs advanced German filter plate production technology and processes, operating 15 automated filter plate production lines capable of manufacturing various specifications of filter plates ranging from 630x630mm to 2500x2500mm. Additionally, we have a dedicated product materials formula research and development center and a filtration laboratory, with a senior filtration expert from Germany serving as our technical director. We utilize a made-to-order production model, allowing us to design and manufacture based on customer requirements.
Material Selection: Filter plates are typically made from polypropylene, polyethylene, and stainless steel to ensure corrosion resistance and high-pressure durability.
Various Specifications:Filter plates come in different sizes and thicknesses and can be customized according to specific application needs, accommodating different types of filter presses.
Hole Structure:The surface of the filter plates is usually designed with specific hole shapes to ensure optimal filtering effectiveness and reduce the resistance to the formation of the filter cake.
Lightweight: Modern filter plates are made from lightweight materials, which facilitate installation and replacement, thereby improving operational efficiency.
